Which of the following radioisotopes is used as anticancerous?

Options

  1. A( Na -24 )
  2. B( C -14 )
  3. C( U -235 )
  4. D( Co -60 ).

Correct answer

D. ( Co -60 ).

Step-by-step solution

Radiation ( ( )-rays) emitted by the radioactive substances ( ( ₂₇ Co ⁶⁰ ) ) destroys the cells. Hence, it is used in treatment of cancer in which the malignant cells are wiped out.
